"Sto lat" (One Hundred Years) is a traditional Polish song that is sung to express good wishes, good health and long life to a person. The song's author and exact origin are unattributed. The song is sung both at informal gatherings (such as birthdays or name days) or at formal events, such as weddings. Frequently, the song "Niech im gwiazdka pomyślności" will be sung afterwards, excluding kids' parties, as the song makes reference to alcohol consumption. At state events it is not unusual to hear it performed by an orchestra or a military band. It is also noted for being an integral part of Polish immigrant culture even long after assimilation.
